Hey people, ive been on a few forums but to no avail in trying to get my newly built comp up and running, and have followed all the advice but no1 seems to have a clue. Ok so here is my predicament. Ive just started, well built, a new PC with the following:

Case: antec 900

Mobo:Asus M2N32-SLi Deluxe NF590 SLI, S AM2, PCI-E (x16), DDR2 533/667/800, SATA II, SATA RAID, ATX

Ram: 1GBGeIL 1GB (2x512MB) PC6400C4 800MHz Ultra Low Latency DDR2 Dual Channel Kit and OCZ 2GB (2 x 1GB) PC2-8500 1066MHz SLI-Ready Edition Dual Channel DDR2

CPU: AMD Athlon 64 X2 Dual Core 5200+ 2.60GHz (Socket AM2)

PSU: coolmaster 600 W igreen power

Graphics Card: geforce 7950GT 512MB

CPU cooler: Arctic Cooling Freezer 64 Pro CPU Cooler

Harddrive: Samsung SpinPoint P SP1654N 160GB ATA-133 8MB Cache (IDE connection)

DVD drive:Optiarc (Sony/NEC) AD-7170S-0B 18x DVD±R, 8x DVD±DL, DVD+RW x8/-RW x6, DVD-RAM x12, SATA, Black, OEM

All of which are pretty quality parts. Anyways the first time i tried a while back to boot it up i had a duff motherboard, it would run ( fans going etc) for about three seconds, then would shut down. through process of elimination i got it down to it either being the motherboard and CPU ( as the grpahics card and RAM worked fine in the comp im using atm) and got a refund for my motherboard and bought a new one ( not off ebay this time) i didnt just buy one, i bought two, the one i was going to finally use and one cheap assed one just to test out the system on. Anyways now ive run into a diff problem. The computer starts up, the fans spin on the case, the CPU and the graphics card, u can hear the harddrive going etc, but when i plug the screen in there is no post, the screen just stays with the power button on orange, indicating nothing is being sent to it. ( the screen is working atm as i am using right now) There is also no beeps coming from the Mobo atall ( ive plugged in speakers yes :P) Anyways, i just thought no way in hell could i have three duff mobo's in a row, two of which were brand spanking new ( i used an antistatic wristwatch the wrong time which kinda rulled out any change of me shocking the parts.) so in pure frustration i went and bought myself ANOTHER CPU, cos i thoguht it must be the component that is wrong. So after all that my question is could it be the CPU thats causing the problems ( just say it was buggered could it cause all of this to happen???) or is it almost definetly the mobo??? could someone please shed some light on this for me, as if there isnt a chance it is the CPU then i have a brand spanking new CPU on my hands with no use for it. lol.

Many thanks,
Alex
P.s i have tried running it outside the box on some cardboard with the bare minimum(CPU, CPU cooler, one stick of ran and graphics card), even without the RAM there is no beeps no nothing,

listen dude, i had exactly the same problem about a year a go, i tried loads of places and no one had a solution, i ended up getting a new motherboard, well, the 3rd actually, i brought the 1st 2 from ebay and the 3rd from ebuyer, the 3rd worked fine. There was nothing wrong with my processor. Hope maybe this helps?
